BBSNews 2007-09-16 -- (IACM) According to basic research of scientists of the National Centre for Scientific Research in Valbonne, France, cannabidiol (CBD) may prevent the development of prion diseases, the most known being BSE (bovine spongiforme enzephalopathy), which is often called mad cow disease. It is believed that the BSE may be transmitted to human beings. In humans, it is known as Creutzfeldt-Jakob disease.

The infectious agent in prion diseases is believed to be a specific type of misfolded protein called prion. Misfolded prion proteins carry the disease between individuals and cause deterioration of the brain. The French researchers reported that the non- psychoactive cannabis constituent CBD inhibited the accumulation of prion proteins in both mouse and sheep prion- infected cells, whereas other cannabinoids were either weak or not effective. Moreover, after infection with mouse scrapie, a prion disease, CBD limited accumulation of the prion protein in the brain and significantly increased the survival time of infected mice. CBD inhibited the nerve damaging effects of prions in a concentration-dependent manner. Researchers noted that CBD may be a promising agent for the treatment of prion diseases.
